The Lowdown
G'day, Rusty here, and I gotta be straight with you – the outlook for Kennebunk Beach for the next couple of weeks is a real bummer. We're looking at a long stretch of flat, unrideable conditions. The water is sitting at a touch warmer than normal for this time of year, about 69°.
Right from the start on Friday, August 14th, it's a no-go with a tiny 1ft swell coming from the SE and a cross-on wind making it choppy. The combined wave energy is a weak 17, and that theme sticks around for days. Saturday the 15th is glassy in the morning, but the swell is only 0.6ft, so there's just nothing to ride. The pattern of small, weak swells with poor wind continues right through the end of the month.
The energy stays in the double digits, never breaking into even moderate territory. There's a brief moment on the morning of Tuesday, August 18th, when we get a clean, offshore wind from the ENE, but the swell is still a pathetic 3ft with a period of 8 seconds – just not enough power to make it worth paddling out. The situation is much the same on the morning of Thursday, August 27th, with a clean offshore wind but a 1ft swell.
The best of what's on offer is a very weak, stray 3ft SE swell on the morning of Monday, August 17th, but it's wind-affected and the period is a short 5 seconds, giving it a combined energy of only 48. It's just not surfable. Honestly, for the whole 16 days, there's no standout window. The forecast is a total blank, and for an area with a fairly consistent spot like this, it's a dry spell you just have to wait out. The forecasts can always change, but for now, leave the board in the shed.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
